Stroller

ABSTRACT

A stroller includes a main frame, a seat, a wheel set, a tray, and a steer grip. The main frame has a handle bar. The seat is disposed on the main frame for holding an infant. The wheel set is attached to the main frame. The tray is disposed on the main frame corresponding to the handle bar. The steer grip projects from a side of the tray and is separate from the handle bar.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/458,169, which was filed on Nov. 18, 2010, and is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a stroller, and more specifically, to a stroller having a steer grip for one-hand steering.

2. Description of the Prior Art

In general, a conventional stroller includes a main frame having a handle bar for pushing, an infant seat, and front and rear sets of wheels. Typically, the rear sets of wheels are fixed in orientation, while the front sets of wheels serve as castors to be able to pivot in any direction. While a caregiver pushes the stroller on a road, especially on a bumpy road, the stroller is less stable directionally due to the pivotable wheels. Although any instability caused by the pivotable wheels can be compensated by gripping the handle bar via the caregiver's two hands, the said two-hand operation may cause the caregiver much inconvenience when the caregiver is confronted with a situation where it is desirable to be able to operate the stroller with a single hand.

Therefore, a handle grip for one-hand steering is applied to a stroller to solve the said problem. For example, U.S. Pat. No. 5,988,669 discloses a handle grip respectively connected to a handle bar and a tray of a stroller for one-hand steering of the stroller. However, in this design, the handle grip additionally occupies gripping space on the handle bar at connection of the handle grip and the handle bar. Thus, this design is inconvenient for the caregiver when the caregiver wants to grip the handle bar to push the stroller.

SUMMARY OF THE INVENTION

Thus, an objective of the present invention is to provide a stroller having a steer grip for one-hand steering to solve the aforesaid problems.

The present invention provides a stroller includes a main frame, a seat, a wheel set, a tray, and a steer grip. The main frame has a handle bar. The seat is disposed on the main frame for holding an infant. The wheel set is attached to the main frame. The tray is disposed on the main frame corresponding to the handle bar. The steer grip projects from a side of the tray and is separate from the handle bar.

These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side view of a stroller according to an embodiment of the present invention.

FIG. 2 is an enlarged diagram of a tray, a steer grip, and a handle bar in FIG. 1.

DETAILED DESCRIPTION

Pease refer to FIG. 1, which is a side view of a stroller 10 according to an embodiment of the present invention. As shown in FIG. 1, the stroller 10 includes a main frame 12, a seat 14, a wheel set 16, a tray 18, and a steer grip 20. The main frame 12 has a handle bar 22 such that a caregiver can grip the handle bar 22 by his two hands to drive the stroller 10 to move forward or backward. In this embodiment, the main frame 12 can be preferably a collapsible frame (but not limited thereto) so that the stroller 10 can be collapsed for storage convenience or opened for carrying and transporting an infant across support surfaces (e.g. floors, sidewalks, streets, or any suitable terrain). As for the collapsible design of the main frame 12, its related description is omitted herein since it is commonly seen in the prior art. The seat 14 is disposed on the main frame 12 for holding an infant. The wheel set 16 is attached to the main frame 12. The wheel set 16 can adopt a common wheel design (e.g. a three-wheel design or a four-wheel design) for a stroller. For example, as shown in FIG. 1, the wheel set 16 can include front sets of wheels 15 and rear sets of wheels 17. The rear sets of wheels 17 are fixed in orientation and the front sets of wheels 15 serve as castors to be able to pivot in any direction. The tray 18 is disposed on the main frame 12 corresponding to the handle bar 22. The tray 18 can be a conventional parent tray in front of the handle bar 22 to give the caregiver a place to store and conveniently access items, such as infant supplies (e.g. water bottles).

In the following, more detailed description for the structural design of the steer grip 20 is provided. Please refer to FIG. 1 and FIG. 2. FIG. 2 is an enlarged diagram of the tray 18, the steer grip 20, and the handle bar 22 in FIG. 1. As shown in FIG. 1 and FIG. 2, the steer grip 20 projects from a side of the tray 18 for steering of the stroller 10 and is separate from the handle bar 22. In this embodiment, the steer grip 20 is preferably aligned with a center line L of the tray 18 and tilted downwardly relative to the tray 18. In such a manner, the steer grip 20 is not only angled to provide an ergonomic natural hand placement, but also provides versatility to a non-adjustable conventional gripping area.

Furthermore, in this embodiment, the steer grip 20 preferably includes a connecting portion 24 and a grip portion 26. The connecting portion 24 is extendedly formed from the side of the tray 18, and the grip portion 26 is detachably connected to the connecting portion 24 (e.g. by a screw-locking method). The grip portion 26 is preferably made of skidproof material (e.g. rubber) and has a plurality of protruding bars 28 arranged alternately, so that the caregiver can hold the steer grip 20 more comfortably and securely.

To be noted, the grip portion 26 can also be integrally formed with the connecting portion 24 instead of being detachably connected to the connecting portion 24 as shown in FIG. 1, so as to make the steer grip 20 have a more compact look. Furthermore, the structural design of the steer grip 20 is not limited to the design that the steer grip 20 is tilted downwardly relative to the tray 18, meaning that the steer grip 20 can be tilted upwardly relative to the tray 18 instead. As for which design is utilized, it depends on the practical application of the stroller 10.

Compared with the prior art, the present invention utilizes the design that the steer grip projects from the side of the tray and is separate from the handle bar. In such a manner, when the caregiver is confronted with a situation where it is desirable to be able to operate the stroller with a single hand, the caregiver can just hold the steer grip for easily achieving one-hand steering of the stroller. Accordingly, operational flexibility and use convenience of the stroller can be further enhanced. Furthermore, as mentioned above, since the steer grip is separate from the handle bar, the present invention can prevent the steer grip from occupying gripping space on the handle bar. In other words, the present invention can further keep the handle bar clear to provide more gripping placements for the caregiver when the caregiver wants to grip the handle bar to steer the stroller, so as to solve the problem aforementioned in the prior art.

Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
